Getting the Hash Code of the Given Index in C#
The Index Structure is introduced in C# 8.0. It represents a type that can be used to index a collection or sequence and it can be started from the start or the end. You are allowed to find the hash code of the specified index with the help of the GetHashCode Method provided by the Index struct. This method returns the hash code of the specified index.
Syntax:
public override int GetHashCode();
Example 1:
// C# program to illustrate the // concept of the GetHashCode() method using System; namespace example { class GFG { // Main Method static void Main( string [] args) { // Creating new indexes // Using Index() constructor var in1 = new Index(1, true ); var in2 = new Index(3, false ); // Getting the hash code // of the given index // Using GetHashCode() method var res1 = in1.GetHashCode(); var res2 = in2.GetHashCode(); // Displaying the index Console.WriteLine( "Hash Code of Index: {0} is: {1} " , in1, res1); Console.WriteLine( "Hash Code of Index: {0} is: {1} " , in2, res2); } } } |
Output:
Hash Code of Index: ^1 is: -2 Hash Code of Index: 3 is: 3
Example 2:
// C# program to illustrate the concept // of the GetHashCode() method using System; namespace example { class GFG { // Main Method static void Main( string [] args) { // Creating and initializing an array string [] greetings = new string [] { "Hello" , "Hola" , "Namaste" , "Bonjour" , "Ohayo" , "Ahnyounghaseyo" }; // Creating new indexes // Using Index() constructor var in1 = new Index(2, true ); var in2 = new Index(3, false ); var in3 = new Index(2, false ); // Getting the hash code // of the given indexes // Using GetHashCode() method var res1 = greetings[in1].GetHashCode(); var res2 = greetings[in2].GetHashCode(); var res3 = greetings[in3].GetHashCode(); // Displaying the index Console.WriteLine( "Index: {0} Value: {1} HashCode: {2} " , in1, greetings[in1], res1); Console.WriteLine( "Index: {0} Value: {1} HashCode: {2} " , in2, greetings[in2], res2); Console.WriteLine( "Index: {0} Value: {1} HashCode: {2} " , in3, greetings[in3], res3); } } } |
Output:
Index: ^2 Value: Ohayo HashCode: -1302855152 Index: 3 Value: Bonjour HashCode: 399419679 Index: 2 Value: Namaste HashCode: 1350085290
